That's what I want a rotisserie for. I'd like to use that to smoke whole turkeys. If the meat's on the rotisserie, and the cooking grates are removed, you can fit one, probably two birds into the cooking chamber and use the SFB for heat and smoke. Of course, you'd have to switch the birds around, right for left, so they cook evenly.

Rotisserie chicken is one of my favorite ways to make chicken. No other method replicates the results. If you want one, get a battery operated machine. I've had mine for twenty years, but have seen them on line recently.
